According to the React Native Documentation:

You don't use a special language or syntax for defining styles. You just style your application using JavaScript. All of the core components accept a prop named style. The style names and values usually match how CSS works on the web, except names are written using camel casing, e.g backgroundColor rather than background-color.

The style prop can be a plain old JavaScript object.

As a component grows in complexity, it is often cleaner to use StyleSheet.create to define several styles in one place. Here's an example:

import React, { Component } from 'react';
import { StyleSheet, Text, View } from 'react-native';

export default class LotsOfStyles extends Component {
  render() {
    return (
      <View>
        <Text style={styles.red}>just red</Text>
        <Text style={styles.bigblue}>just bigblue</Text>
        <Text style={[styles.bigblue, styles.red]}>bigblue, then red</Text>
        <Text style={[styles.red, styles.bigblue]}>red, then bigblue</Text>
      </View>
    );
   }
 }

const styles = StyleSheet.create({
  bigblue: {
    color: 'blue',
    fontWeight: 'bold',
    fontSize: 30,
  },
  red: {
    color: 'red',
  },
});

And of course, the styles do not need to be in the same file as the component. You can abstract them to a separate file and then simply export them from there and import where needed.
